7 Applicationfiled August 12, 191a,.

T all whom it may concern I I Be it known that I, Gnonen MILLER, a citizen of the Uni ted States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Windows, of which the following is a specification. 7

This invention relates to certain novel and useful improvements in windows, and the object of the invention is to produce an in expensive device of this character in which the sashes are adapted for vertical travel, as

' usual, within the sasl1fi'ame,' and wherein the sashes may be readily swung'in a horizontal plane to open position in the room, thus permitting free ventilation and the ready cleaning of the windows. Another object of my invention is to pro vide a construction which can be applied to old window frames and sashes, so as to convert the same into a hinged window and also to provide improved means for retaining the sashes in position in the window frame as well as for locking such sashes within the sash-grooves to prevent their displacement when the windows are swung open.

Another object of my invention is the provision of novel mechanism for swingingly and slidably mounting the sashes in the frame and locking such sashes in a selected or desired position, and also to provide means whereby the movement of the sashes is limited during the opening of the window. By the employment of my invention, the sashes may not only slide vertically in the usual manner, but may be swung bodily inwardly of the room at selected times and at any position in thewindow frame. For example, when it is desired towash the window panes, the sashes may be swung inwardly at right angles to the frame so that the person standing within the room may readily perform the cleaning operation without the danger or inconvenience encountered when it is necessary to mount the ledge or window sill for such purpose. And the mechanism I utilize for so operating and latching the sashes is very simple, so that it may be readily applied to window frames and sashes of the usual construction.

With these and other objects in view my invention comprises the combination and arrangement of the various details as hereinafter described, shown in the accompanying drawings and specifically pointed out in th claims.

In the drawings: Figure 1 is a vertical section of a window-embodying my invention. Fig. 2 is similar view showing the sash in position for cleaning. Fig. 3 is a fragmem tary side elevation of the keeper plate afliXed to the parting strip. Fig. l is a detail top plan view of the lower sash broken away. Fig. 5 is a detail perspective view of the upper portion of the slide for the lower sash. Fig. 6 is a side elevation of the lower sash. Fig. Tis a vertical sectional view of the two sashes, theupper sash being in a lowered position. Fig. 8 is a fragmentary side eleva tion of the lower sash before the key is inserted. Fig. 9 is a fragmentary view similar to Fig. 8 showing the spring tongue in position in the recess in the metal strip. Fig. 10 is a detail horizontal sectional viewon the line 10-40 of Fig. 2 looking in the direction of the arrows. F ig, 11 is a detail horizontal cross section through the lower sash and slide showing the weatherproofing joint. Fig. 12 is a sectional view on the line 12-12. of Fig. 7. Y A

The reference numeral 1 designates an or.- dinary window frame provided at the opposite vertical sides thereof with the usual sash-grooves 2 2, formed between the inter' mediate vertical parting strips 3 and the inner and outer strips 4 and 5, respectively, which are fitted to the window-frame in the usual manner. The lower sash 11 is pivoted at 12 to a slide 9 whereby it may, under proper conditions, be swung on the pivot 12 into the room to facilitate the cleaning thereof. In order that there may be a weatherproof joint between the sash and its slide 9 I secure to the slide a metal strip 15 having its inner marginal edge 17 rebent to form a socket into which the inner edge of the metal strip 19, secured to the side; stiles of the sash, projects thereby forming a weatherproof joint. The upper sash 10 and the slide bar 8 are also provided with metal strips 14 and 18 similar to the strips 15 and 19 described in connection with the lower sash, 16 being the rebent marginal edge.

At the upper end of the plate 15 a recess ried by the plate 23 which is suitably secured to and covering the upper end of the slide 8. By means of the hook 22 the sash 10 is held in position on the slide 8 against accidental relative movement thereto.

At the upper end of the slides 8' and 9a 6 is a keeper plate mounted on the parting strip 3 and provided with an elongated slot 7 through which the key 25 passes when it is inserted to disengage the spring hooks 21 and 22; said slot being alined with the grooves 24; in the upper ends of the slides 8 and 9. The keeperplate 6 is provided with locking bolt openings 27 and, 28 through which the bolt 29 is adapted to pass; said bolt being mounted ina plate 30 which has an elongated slot in which the bolt operating knob 31 projects, the movement of the bolt being limited by the knob engaging the ends of the said slot in the plate, Preferably, as shown, the spring hook 21 is carried by the plate 30. lhe slide 8 is provided with openings 32 and 33 constructed to receive the end of the bolt 29 whereby the upper sash may be locked in various positions for the purpose of ventilation.

The sashes being in their normal position the key 25 is inserted in the groove 2% of the lower sash until its inner end has entered the slot 7 of the keeper plate 6 thus raising the spring hook 21 out of engagement with the recess 20 whereupon the sash may be swung inwardly into an open position in the room. The key 25 also serves to limit the upward movement of the slide by engaging the upper end of the slot 7 of the keeper plate 6, whereby the sash is held in position for cleaning the glass.

In order to clean the glass of the upper sash it is lowered and the key is inserted farther into the groove 21 thus raising the spring hook 22 out of engagement of the recess 26 whereupon the sash is lowered inwardly. By means of the key 25 the movement of the slide 8 is limited by engaging with the upper end of the slot 7 of the keeper plate 6 as described in connection with the lower sash.

When it is desired to lock the windowthe bolt 29 is pressed forward by the knob 31 until the inner end of the bolt enters the opening 33 in the slide of the upper sash. For purposes of ventilation the lowersash may be lowered and the bolt 29 projected into the opening 32 in the slide of the upper Copiesof this patent may be obtained for five cents each, by addressing the sash thereby locking the said sash in open position.

I claim:

1. In a window the combination with an upper and a lower sash, a slide pivotally connected to each sash, means for holding the sashes and slides against accidental relative movement, and a key adapted to operate said means whereby the sashes may be swung relatively to the slides and means engaged by said key to limit the upward movement of the slides when the sashes are swung.

2. In a window the combination with an upper and a lower sash, of a slide pivotally connected to each sash, a key guide way in the upper end of each slide, means locking the sashes and slides against accidental relative movement, a key adapted to slide in said guide ways and operate said locking means whereby the sashes may be swung relatively to their slides into position for cleaning.

3. In a window the combination with an upper and a lower sash, of a slide pivotally connected to each sash, a key guide way in i the upper end of each slide, means locking each sash to its slide against accidental relative movement, a keeper plate secured to the parting strip of the window frame and provided with an elongated slot, a key adapted to slide in said guide ways in the slides to unlock the sashes from the slides, and pass through said elongated slot whereby the sashes may be swung into cleaning position and the slides locked against movement by the engagement of the key with the upper end of said elongated slot.

1. In a window the combination with an upper and lower sash, of a slide pivotally connected to each sash, a key guide way in the upper end of each slide, metallic strips secured to the abutting faces of the slide and sash, a recess in the upper end of the metal strips on the slides, a spring locking tongue carried by the sash adapted to enter said recess and lock the sash and slide against relative movement, a keeper plate secured to the parting strip of the window and pro vided with an elongated slot and a bolt opening at each end of the slot, a key adapted to slide in said guide ways to disengage the locking tongues from their recesses and pass through the said elongated slot, whereby the sash may be swung to cleaning position and the slides locked against movement by the key engaging the upper end of the slot. r

In testimony whereof I allix my signature in presence of two witnesses.
